Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038728, here are decompositions:

7 + 1038721 = 1038728
37 + 1038691 = 1038728
109 + 1038619 = 1038728
127 + 1038601 = 1038728
139 + 1038589 = 1038728
199 + 1038529 = 1038728
241 + 1038487 = 1038728
307 + 1038421 = 1038728

Showing the first eight; more decompositions exist.
